Abstract

This paper proposes a multi-view three-dimensional display method based on a scanning imaging system with the light-intensity characteristic recorded by an improved flatbed scanner. Within the effective scanning depth of the imaging sensor, two transmission images are each simultaneously acquired by two linear CCD modules with different focal planes. Then the phase gradient information of the target can be obtained by an appropriate retrieval algorithm. Further, the multi-view three-dimensional effect is presented through dynamic angles of view. Theoretical analysis of this method is discussed, and experiments are carried out by building a scanner. The experiment results are presented with an algae specimen and transparent beads. We hope this method can be applied to present the three-dimensional effect of objects of flat translucent multilayer structure with a wide field of view.
